Missouri Constitution Section

Right to keep and bear arms, ammunition, and certain accessories--exception--rights to be unalienable.

Section 23. That the right of every citizen to keep and bear arms, ammunition, and accessories typical to the normal function of such arms, in
defense of his home, person, family and property, or when lawfully summoned in
aid of the civil power, shall not be questioned. The rights guaranteed by
this section shall be unalienable. Any restriction on these rights shall be
subject to strict scrutiny and the state of Missouri shall be obligated to
uphold these rights and shall under no circumstances decline to protect
against their infringement. Nothing in this section shall be construed to
prevent the general assembly from enacting general laws which limit the rights
of convicted violent felons or those adjudicated by a court to be a danger to
self or others as result of a mental disorder or mental infirmity.
